Orphnaecus is a genus of tarantulas that was first described by Eugène Louis Simon in 1892. They have close to fifty lanceolate stridulatory spines on the chelicerae, known as "strikers". The male embolus has a single strong retrolateral keel. It was considered a senior synonym of Chilocosmia and Selenobrachys; however, more recent studies have found the three genera sufficiently different to remain separate.
